Question 19

A block with a mass of 55 kg is pulled with a force of 220 N to the right. Assuming a frictionless surface, what will be the acceleration of the block?

a
22 m/s2

b
9.8 m/s2

c
0.25 m/s2

d
4.0 m/s2

To find the acceleration of the block, we can use Newton's second law of motion, which states that the force applied to an object is equal to the mass of the object multiplied by its acceleration (F = ma).

Given:
- Mass (m) = 55 kg
- Force (F) = 220 N

We can rearrange the formula to solve for acceleration (a):

\[ a = \frac{F}{m} \]

Now, plugging in the values:

\[ a = \frac{220 \, \text{N}}{55 \, \text{kg}} \]

Calculating this gives:

\[ a = 4 \, \text{m/s}^2 \]

So the acceleration of the block is 4.0 m/s².

The correct answer is:

**d) 4.0 m/s²**.
